EDWIN B. STIMPSON, OF BROOKLYN, NEW YORK, ASSIGNOR TO EDVIN' B. STIMPSON COMPANY, OF BR-OOKLYN, NEIV YORK. I

RIVET-SETTING MACHINE.

Application filed June 16, 1921. Serial No. 477,968.

To all whom it may concern:

Be it known that I, EDWIN B. STIMrsoN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Rivet-Setting Machines, of which the following is a specification.

This invention relates to rivet setting machines, of the kind in which the work to a be riveted is sustained by a rigid work support or post, while the rivet setting force is applied by a plunger toward the work support or post to cause the rivet to first 1 pass through the work and then be set.

It is'one' of the objects of my invention to provide a structure in which the work support or post is desirably fixed and rigid and in which the rivet supplying and setting mechanisms are a unit, supported by the machine frame in adjustably fixed relation to the work support. I also contemplate the use of work supports or posts of different lengths, and the adjustable mounting thereof, so that a considerable range of adjustment-combinations is made possible.

Another object is to provide for ready assembling and disassembling of the rivetsupplying and feeding unit from the machine frame, while securing the utmost rigidity of connection when the parts are assembled.

Other objects and aims of the invention, more or less broad than those stated above,

together with the advantages inherent, will be in part obvious and in part specifically referred to in the course of the following description of the elements, combinations, arrangements of parts, and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims.

In the accompanying drawings, which are to be taken as part of this specification, and

in which I have shown merely a preferred form of embodiment of invention,

Figure 1 is an elevation of a machine embodying my invention;

Figure 2 is an elevation of the rivet supplying and setting unit, detached;

Figure 3 is an elevation of the same, taken at right angles to Figure 2; and

Figure 4 is a detail perspective of the part of the frame to which the rivet supplying and setting unit is adjustably ,secured. i Referring to the numerals on the drawings, a machine frame is indicated at 5, having an arm 6 on the outer end of which the rivet supplying and setting unit is carried, and an arm 7 beneath the arm 6, carrying at its end a vertically adjustable work supporting post or spindle 8. The outer end face of arm 6 (Figure 4) isprovided, in the present instance, with a cruciform rib projection 9, with vertical ribs 10 and horizontal ribs 11, and the arm 6 also carries lugs 12 between which an operating lever 14 is pivoted. i

A rivet supplying and settingunit is shown in Figures 2 and 3 and comprises a block 15 for attachment to the end of arm 6, a plunger or driver 16 reciprocating through the block, a rivet hopper 17,'a raceway 18 through which rivets pass to a car rier 19, andthe related partsand connections necessary for'the operation of the machine, but which need not be further described because they form no part of the presentvinvention. It will be understood, however, that rivets are supplied one by one to carrier 19, and that plunger 16 forces the rivet to and through the work supported on post 8, the carrier being made in separable sections to permit of the release of the rivet therefrom as the plunger descends.

In order that the distance between the carrier 19 and the post 8 may be varied (or the distance between post 8 and the limit of the downward stroke of plunger 16'), the outer face of the block 15 is provided in the present instance with a vertical groove 20, corresponding in width to the ribs 10, and a plurality of horizontal grooves 21, each of width corresponding to horizontal ribs 11, and intersecting the vertical groove 20. The block is also provided with elongated openings 22, through which are passed bolts 24: entering bolt holes 25 in the end face of arm 6. In every adjusted relation of arm 6 and block 15 the vertical ribs 10 will lie within the single vertical groove 20, while the horizontal ribs 11 will lie within the particular horizontal groove 21 which may be selected to establish the desired distance relation between post 8 and carrier 10. Since there is but one vertical groove 20 it will be impossible to connect the parts improperly, so far as vertical alinement is concerned, While the interlocking relation between ribs and groovcs insures the utmost rigidity after the bolts 24: are in place.

Inasmuch as many changes could be made in the above construction, and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, it is in tended that all matter contained in the above description or shown in the accompanying drawings shall be interpret-ed as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the inven tion which, as a matter of language, might be said to falltherebetween.

I claim:

1. In a rivet setting machine, a frame, a Work supporting post carried by the frame, an arm on the frame having its free end above and in spaced relation to the work supporting post, a rivet supplying device, a rivet setting devi.ce,a supporting plate common to the rivet supplying and rivet setting devices whereby the two devices are assembled as a unit, the plate member and the end of the arm member being provided with means for holding the plate positively locked tothe arm in a selected one of a plurality of positions at different distances above the post, said means including vertically disposed interengaging portions of the two members that are always in the same vertical line when the parts are connected.

2. In a rivet setting machine, a framehaving an arm, a work supporting post carried by the arm, a second arm on the frame extending over the first arm and having an attaching portion on its end face, and a rivet supplying and setting unit having an attaching portion interengageable with the attaching portion of the second arm, one of the attaching portions comprising a vertical groove and intersecting horizontal grooves, and the other attaching portion comprising ribs in cruciform arrangement.

3. In a rivet set-ting machine, a frame having an arm, a work supporting post carried by the arm, a second arm on the frame extending over the first varm and having an attaching portion on its end face, and a rivet supplying and setting unit having an attaching portion interengageable with the attaching portion of the second arm, one of the attaching portions comprising a vertical groove and intersecting horizontal grooves, and the other attaching portion coi'i'rprising ribs in cruciform arrangement, and bolts passing through the unit and into the end face of the second arm.

In testimony whereof I aft-ix my signature.
